The factors responsible for postoperative astigmatism — wound compression and wound gape — are discussed and illustrated for a number of suture incision combinations. Variability is pronounced. Midlimbal incisions sutured with 8‐0 virgin silk had a range of 8D at four days, 8.5D at four weeks and 9D at three months. Nylon 9‐0 double continuous, tied normally, had 8D at four days, 7D at four weeks and 7.5 D at three months. The same suture tied tightly gave a range of 5D at four days, 7.5D at four weeks and 6D at three months. Methods of control and Correction are discussed and illustrated with case histories.
